1. An optical imaging lens, from an object side to an image side in order along an optical axis comprising: a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a seventh lens element, wherein the first lens element to the seventh lens element each has an object-side surface facing toward the object side to allow an imaging ray to pass through as well as an image-side surface facing toward the image side to allow the imaging ray to pass through, wherein:
a periphery region of the image-side surface of the first lens element is concave;
an optical-axis region of the object-side surface of the second lens element is convex and a periphery region of the image-side surface of the second lens element is concave;
an optical-axis region of the image-side surface of the third lens element is convex;
the fourth lens element has negative refracting power and an optical-axis region of the object-side surface of the fourth lens element is concave;
an optical-axis region of the object-side surface of the fifth lens element is concave and a periphery region of the object-side surface of the fifth lens element is concave;
a periphery region of the object-side surface of the sixth lens element is concave; and
the lens elements included by the optical imaging lens are only the seven lens elements described above,
wherein, T2 is a thickness of the second lens element along the optical axis, T6 is a thickness of the sixth lens element along the optical axis and T7 is a thickness of the seventh lens element along the optical axis, and the optical imaging lens satisfies the relationship: (T2+T6)/T7≤2.200.
